MORE INFORMATION

Web servers use cookies to store and retrieve information about your computer by using Hypertext Transfer Protocol (HTTP). This information can include any information that can be transmitted by using the HTTP protocol (for example, your computer's Internet Protocol [IP] address, your operating system, your browser type, the referring page, the number of repeat visits to a page) or your personal preferences for that Web site (for example, if you choose to display local weather on your MSN, The Microsoft Network, Start page or if you choose to have a Web site remember your password when you return to that site).

Custom Pages

The MSN custom page is an example of a large cookie. After you select the options that you want for your page, the server writes that information in your cookie to retrieve when you visit the page later.

Shopping

If you visit a site that has a shopping cart feature in which you can store items that you want to purchase, a cookie tracks what you put in the cart. If you need to leave the site and come back later, your shopping cart contains the same items that you placed it before you left the site.

Tracking

A cookie can track repeat visits to a page.

Cookies are saved in the Windows\Cookies folder in the Username.txt file, where Username is your user name on that site. The name of the file may vary depending on the name of the current user, the name of the user for whom the cookie is written, and the different pages that offer cookies to your computer.
